HALEU

High-Assay Low-Enriched Uranium (HALEU) is a type of nuclear fuel that is enriched to a level between 5% and 20%, which is higher than the 3% to 5% typically used in existing light-water reactors. It is considered essential for the next generation of advanced small modular reactors (SMRs) and micro-reactors due to its ability to provide more power in a smaller footprint and longer core life.
